【題目】下列關于人口的敘述,錯誤的是( 。

A.人口增加可以提供更多的勞動力,因此不必限制人口的數(shù)量

B.為了滿足增加人口所需的糧食,亂墾濫伐會加重水土流失

C.人口自然增長率較高的國家一般都是發(fā)展中國家

D.目前人口最多的大洲是亞洲

【答案】A

【解析】

地球上的自然資源是有限的,人類在地球上的生存空間同樣是有限的。世界人口的急劇增長,社會經(jīng)濟的迅速發(fā)展,給資源和環(huán)境造成了空前的壓力,也給人類的生存和發(fā)展帶來了一系列的問題。人口的自然增長主要是由出生率和死亡率決定的。人口自然增長率與經(jīng)濟發(fā)展水平有密切聯(lián)系。近幾十年來,隨著生活和醫(yī)療水平的提高,嬰兒死亡率逐漸降低,人的壽命不斷延長。這樣就促使世界人口迅速增長。一般來說,經(jīng)濟發(fā)展水平高的國家,人口的自然增長較慢;經(jīng)濟發(fā)展水平低的國家,人口的自然增長較快。亞洲、非洲和拉丁美洲的一些國家,人口增長過多過快,給社會經(jīng)濟發(fā)展造成很大壓力,使居民的就業(yè)、居住、教育、醫(yī)療等問題難以解決,還有一部分國家則長期處于貧困狀態(tài)。目前人口最多的大洲是亞洲。在歐洲的一些國家,比如意大利、德國和瑞典,近些年來人口一直處于負增長狀態(tài),已引起勞動力短缺、人口老齡化等問題。故選:A。

【題目】 I saw Tom Sawyer on the way to the town. When he saw me he looked frightened. “Huck! Why have you come back to scare me? I never hurt you,” he said. “I haven 't come back. Tom. I've never been away.”

“Aren't you a ghost?”

“No, it was a trick.” I said.

Then I told him that I wanted to rescue(營救) Jim—a slave(奴隸).

“I'll help you,” Tom replied excitedly. He loved an adventure more than anything else in the world.

When we got back to the farm, Tom said that he was Sid, Tom's younger brother. Aunt Sally was surprised to see him but was happy to have his two nephews(侄子).

That night, Tom and I went out to look for Jim. There were lots of huts in the garden. One of the huts was locked. So we guessed Jim was locked in the hut. We dug a tunnel under the wall of the hut that night. Finally, we succeeded. Jim was very surprised to see us.

“Hello, Jim!” Tom said. “But we aren't ready to do it yet, you'll have to wait a couple of days.” “Don't worry! you'll soon be free!”

Then we came back and talked about a plan to get away.

“I'm going to write a letter to Uncle Silas,” Tom said.” “Of course I won't sign it. It'll be anonymous(匿名的). I’m going to warn him that somebody's planning to steal the runaway slave .”I didn't understand why we had to look for trouble but I didn't say anything. “Well, Huck, if Uncle Silas knows, he'll try to stop the thieves,” says Tom.

So Tom wrote the letter and I put it under the front door. Uncle Silas found it in the morning. After reading it, he went out at once. At night, we successfully rescued Jim. We are very happy because Jim is a free man now. Though Tom got a bullet(子彈)in my leg, it was a great adventure.
